iApplication filed September 16, 192-7. 'Serial No. 219,829.

This invention relates to deflectors for' directing slices away from therotary knives ofsli'cing machines, and has for one of its 1 objects theprovision of a support for deflectors :of this nature which will holdthe deflector in position adjacent the face of the slicing knife so thatthe deflector will not be moved out of position by the slices engagingtheedge of the deflector.

which the force of the slices, as'they are being cut, tends to hold the.deflector n its locked position. I A further object is to provide, adeflector which will overlap its support when in operative position to'preventany gap or open space between the deflector and support.

A further object is to provide anlad ustable support for the deflect-orwhich will permit'the edge of the deflector to be .adjusted relative tothe I face of the slicing knife.

Other objects and advantages will appear from the following description.

The invention is exemplified in the combination and arrangement of partsshown inthe accompanying drawing and'described in the followingspecification, and it is more particularly pointed out in the appendedclaims. I c

In the drawing- I Fig. l is an elevation of a portion of a slicingmachine knife showing one embodr ment of the present invention appliedthereto; 1

Fig. 2 is a top plan view of thedeflector shown in Fig. 1; 1

Fig-3 is a section enline 3-3 of Fig. 1; and s Fig. 4 is a'view similarto F1g; 3', but showing the parts in a CllffBIQIIt' pOSItiOILThis'invention is somewhat similar to the device shown in my priorapplication, SerialNo. 141,484, filed October14, 1926, but shows adifferent form of pivotal support forthe'deflector. j v

The numeral 10 designates the bearing support fora slicing machine knife11 which is journaled at 12 on the support 10. A plate 1'3Lis securedtothefside of the support 10 by screws 14- and is provided wi'thflaterally projecting brackets 15 having bearing openings 16 therein.The brackets 15 are pro- A further object is to provide a deflectorwhich is locked in operative position and 1n.

vided with slots 17 which "communicate with the inner 's'ides of theopenings '16. The deflector. plate 18 '-1svprovided with inward- 1yprojecting ears l9 and 2O. .The ear 19 carries a downwardly projectinglug 21 of,

a-size and shape to fit into the opening 17 in the lower bracket 15. Theear 20 carries an upwardly-projecting lug 22 shaped to fit within theopening 17 of the upper brack-' et'15. Spring rings '23 disposed in theopenlugs 16 in the brackets 15 retain the lugs 21 and 22in position inthe slots 17-. The'rings 23 .areopen at one side and the lugs 21..and

,22. are;provided with rounded edges which 'i engage-the open ngs in.theyrin-gs. .=So long as the lugs 21,-and 22 are positioned intheslots; '17, the deflector 18 will'beheld in placeagalnst thefaceofqtheknife 11. When it is desired toswingthedeflectoroutwards 1y away fromthe knife, this may be done by pressing the defiectonto the, right, asviewed in thefdrawing, to m'oVethe lugs21. and 22 through the openings{in the. rings 23 until ,they occupy a position within the interior ofthe rings 23, as shownjin Fig.

4. The deflector l8maylthen be swung'outwardly, as indicated in Fig, 4,.the rings '23 rotating in the openings 16; to provide a pivotal supportfor-the deflector 18. ,The deflector 18 is provided with an opening24Jto ,permitthe insertion'of the operators thumb or fingers to shiftthe deflector for moving the lugs 21 and 22 into "and out of engagementwith the slots 17. A reinforc ing bracket 25 surrounds the opening 24'and bracesfthe ears"191and 20, which support the lugs 21 and 22. i

.In-tghe operativeposition of the deflector,

the lugs '21 and 22 are engaged invthe slots 17 and the rounded ends ofthe lugs register with the gaps in thefrings 23am]. the deflector isthus locked against turning movement. When'the vdeflectoris shiftedtoward the edgeof the knife to release the lugs from theslots-'17,}therings :23 will be. sprung outwardly into frictionalcontact with the inner faces of the openings16 an'd'thus serve tomaintain the deflector in any position into which it may be swung. 'Oo-operating stops '26 and 27 on thedeflector 18 and the supportingbrackets 15, respectively, are. prov-ided for guarding againstaccidentalmove- I ment of the" deflector into- "contact with the face "of'the'jknifeg When the deflector is shifted to the right as viewed in thedrawing out of its operative position, the stops 26 on the deflectormove into a position which registers with the stops 27 the deflectorbeing thus prevented fromswinging further toward thelknife" than theamount determined by thestops 27. Cover plates 28 are fitted on theouter surfaces of the brackets to close the openings 16 and preventingress of grit to the rings 28. The upper cover plate is removed inFig. 2 for the purpose of clearance. Openings 29 are cut inthe walls ofthe brackets 15 to permit the lugs 21 and 22 to pass when fitting thedeflector into position in the supporting brackets or when removing thedeflector from its brackets. The plate 13 is attached to the knifebracket 10 by screws 14, as previously explained, the

' screws being arranged to permit the plate to its: adjusted positions.

inclination of the deflector to the knife can be adjusted at will. Itshould be noted that when the deflector is in its operative positionmove through a slight angle and a grub screw 30 is provided tohold theplate 13 in By this .means the the pivotal point thereof is movedback'toward the support 10 to such ZL'POSIUOII that the rear edge of thedeflector overlaps the supporting member so that no joint is visiblebetween the deflectorand support.
